Crystal structures of a rhodamine derivative in its closed and open spirolactam ring forms were developed, which allows selective and sensitive detection of Cu2+ ions at a micromolar range in neutral medium. The chemosensing properties of the probe through a pentacoordinate Cu2+ ions were proven by spectroscopic and theoretical analysis. The spirolactam ring opening as the Cu2+selective sensor was applied to spinach (Spinacia oleracea) to estimate the accumulation of copper as copper(II) in the plant.

Zhang, Jingyu; Xia, Wei; Huda, Saskia; Ward, Jas S.; Rissanen, Kari; Albrecht, Markus (Wiley, 2021)Herein, a copper(II)-catalyzed dearomative cyclization amination of N-(2-aminobenzoyl) indoles is presented. Under mild reaction conditions, the cyclization proceeds to afford tetracyclic indolines by forming a new C−N ...
